To (ti/Z whom it may concern.-

Be it known that I, FRANK M. THOMPSON, a citizen of the United States, and a resident of East Liverpool, in the county of Oolumbiana and State of Ohio, havemade certain new and useful Improvements in Ventilators, of which the following is a specification.

My invention is an improvement in venti- Fig. 2 is a detail sectional view illustrating the connection between the outer end of the deflector and the support. Fig; 3 is a detail perspective view of the lower portion of the outer end of the deflector. Fig. 4 is a detail bottom plan view of the outer end of the support. Fig. 5 is a detail section taken on the line 5 5 of Fig. 2 of the outer end of the support, and Fig. 6 is a detail perspective view of the lower portion of the inner end of the deflector.

In carrying out my invention I provide a deflector A for directing the wind into the room and a support B, extending outwardly from the window and adapted at its outer end to form a pivotal support for the outer end of the deflector A. The deflector A is preferably made of the sections A and A sliding upon each other, so they can be adjusted as desired, and the outer section A is provided at its outer end with a depending tenon A whose lower end has a lateral stud A", the tenon and its stud being adapted to operate in a keyholeslot B' at the outer end of the outer section B of the arm B, said arm being formed in sections B and B sliding upon each other, as shown. The tenon A is enlarged near its upper end at a forming the downwardlyfacing shoulder a, which rests upon the section B of the arm B, the enlarged. portion a of the tenon operating in the guide, presently described, provided on the section B of the arm B. By the described construction the deflector A is pivoted vertically at its outer end to the arm B, so it can swing from the position shown in Fig. 1, where it abuts one side of the window, to an opposite position, in which it will abut the other side of the window. At the same time the stud A on the lower end of the tenon A operates to prevent the accidental withdrawal of the tenon A from the arm B, except when the deflector and arm are in alinement, which is not likely to occur in the practical use of the invention. The guide O on the outer end of the arm B is flared at O to guide the outer end of the deflector A into the position in which its tenon may be inserted in the opening B" in the section B in applying the deflector to its supporting-arm. 7

As shown and preferred, the outer end of the section B has a dropped portion 5, increasing the bearing for the tenon A It will also be noticed that the enlarged portion a of the tenon holds the body of the outer end post of the section A sufliciently high to permit the deflector to swing over the opposite sides of the guide O in adjusting from one position to the other in the use of the invention. The sections B and B are provided with boxings B, whereby they are tclescoped and can slide along each other to adjust the device out to any extent, and a clamping-screw B may be provided for securing the sections B and B in any desired adjustment. In practice the arm B may be secured by screwing or otherwise t'astening the inner end of the section B to the window-sill, as indicated at in Fig. 1.

The deflector A has its sections A and A slidable upon each other and supplied with coverings A which may be of sail-cloth or other suitable textile or other material.

In the use of my invention the deflector will adjust automatically, according to the direction of the wind, and will bear at its inner end againstone side or the other of the window-frame, projecting as it does at such end slightly within the window, as shown in Fig. 1. I provide such inner end of the deflector on its opposite sides with buffers or cushions at D, of rubber or other soft material, to ease the blow when the deflector adjusts to bear against the window-casing, and I also provide on the under side of the deflector at its inner end a soft or yielding foot E to bear upon the window-sill and operate as a brake to prevent any undue vibration of the deflector when it is adjusted to bear against one or the other side of the window-frame. This brake-cushion E is movable vertically, being in the construction shown carried on a rod E, movable vertically in guides E on the inner end bar of the deflector, as shown in the drawings. This brake operates to steady the deflector against movement to one side or the other of the win- (low, but does not prevent the automatic shift-.

Patent, is-

1. The improvement in ventilators herein described comprising the support composed of inner and outer sections slidable one upon the other, the outer section being provided near its outer end with the keyhole-slot and on its upper side with a guide having flared portions to direct the outer end of the deflector, and the deflector composed of inner and outer sections slidable upon each other, the outer section being provided at its outer end with a depending tenon having a spur at its lower end and adapted to fit in the opening in the outer supporting-section, said ten on having at its upper end an enlarged portion forminga shoulder to rest upon said supporting-section and holding the main portion of the deflector above the guide on the support,

and cushions on opposite sides of the deflector at its inner end, and the yielding brake at the under side of such deflector at its inner end substantially as and for the purpose set forth.

2. A ventilator for use on windows comprising a longitudinally-adjustable support, and a longitudinally-adjustable deflector pivoted at its outer end to said support and arranged to shift at its inner end from side to side of the window substantially as set forth.

3. The combination with a deflector shiftable at its inner end from side to side, of the cushioning-brake, an upright rod supporting said brake, and guides on the deflector in which said upright rod is movable vertically substantially as set forth.

4. The combination in a ventilator with the support having an upright keyhole-slot, of the deflector provided at its outer end with a depending tenon operating in said slot and havinga spur to flt the wing thereof substantially as set forth.

5. A ventilator substantially as described comprising the support having at its outer end an opening for the tenon of the deflector and the deflector having its tenon formed to pivot in said opening substantially as set forth.

6. The combination of the support having a pivot-opening and the deflector having a tenon pivoting in said opening and means at the upper end of said tenon whereby the body of the deflector is elevated above the guide substantially as set forth.

7. The combination in a ventilator of a support consisting of longitudinally-adjustable sections, and a deflector pivoted at its outer end to the outer one of said sections and said sections is pivoted substantially as set forth.
